Greetings,
Now that I had a short nap here is some info on the new changes and how they affect SPAM.
You will notice that some of the emails will have a tag added to the subject line of SPAM-LOW or SPAM-MED. The new mail server has three threshold settings: Low, Medium & High. Those determinations are made by “weighting” each piece of mail.
For example we currently are assigning the following weights (links at the bottom that describe these type of tests:
Tests Weight
Bayesian Filtering 15
SPF
SPF-Pass -15
SPF-Fail 10
SPF-SoftFail 5
SPF-Neutral 0
SPF-PermError 0
SPF-None 0
Reverse DNS 10
Blacklists (RBL)
AHBL 10
DSBL 10
NJABL 15
ORDB 10
SpamCop 10
SpamHaus SBL-XBL 10
